Concrete & Fiberglass Tanks for Septic Systems, Wastewater Treatment & Water Systems

Since 1951, locally owned and operated Selvage Concrete Products has been producing and selling traffic and non-traffic rated, IAPMO certified residential and commercial tanks for water and wastewater management in northern California. As one of the area’s leading manufacturers and sellers of concrete and fiberglass tanks, we serve eleven counties in the greater Bay Area including Contra Costa, Lake, Marin, Mendocino, Napa, San Francisco, San Mateo, Santa Clara, Solano, Yolo and Sonoma.

Septic & Sump Tanks

We stock wastewater tanks in concrete or fiberglass from 500 gallons up to 2,000 gallons, and we can produce or supply much larger ones for special orders. All our concrete tanks are designed by structural engineers and are IAPMO certified and meet Uniform Plumbing Codes and ASTM standards. Manufactured by us at our Santa Rosa location, our tanks meet all state and local regulations and are built to the highest quality standards. We also specialize in delivering them to difficult-to-access locations. All this and our pricing is competitive with the market. Bottom line, our higher quality, easier delivery and comparable pricing adds up to higher value for you.

Wastewater Treatment Systems

We’re devoted to providing customers with high-quality wastewater management products that will last for many years. Manufactured to NSF-40 standards, our treatment components are backed by strong limited lifetime warranties so you simply can’t get better wastewater treatment products at any price.

Grease Interceptors & Sand/Oil Separators

The professionals at Selvage Concrete really know grease traps and interceptors. We can advise on the proper usage of either of these kinds of wasterwater treatment technologies.

Water Tanks & Troughs

Whether you’re building a single or multi-family home, we have the potable or non-potable water tank products you need. If it’s watering troughs for livestock you need, we’ve got you covered there, too. Call us or stop by our offices to talk with our staff about your residential or commercial water tank needs today.
